The Lowdown
Alright, folks, Rusty here. Let’s be straight with you—this outlook for our neck of the woods is a tough one. We’re looking at a long stretch of small, weak, and mostly messy conditions that really aren’t doing us any favors.
Right off the bat, from Tuesday the 25th all the way through to Friday the 4th of September, there's barely a whisper of decent surf. The waves are tiny, mostly under 3 feet, and the wind is almost always onshore or cross-onshore, making things choppy and bumpy. The water temp is sitting at 66°, which is about a degree and a half warmer than normal for this time of year, so at least it feels a little more comfortable while you’re sitting there waiting for a wave that never comes.
The first real glimmer of hope doesn’t show up until Friday the 4th of September. That afternoon at Kennebunk Beach, we finally get a bit of a pulse. The swell is coming from the southeast at 2 feet, but the period is a solid 10 seconds, which means it’ll have a bit more push. The wind swings offshore from the northeast at 9 mph, which is exactly what you want to see—clean lines. The combined wave energy is moderate at 164, and while the surf is still described as "very ordinary," it’s the best we’ve got by a long shot. This is the standout for the whole 16-day run. It’s not going to be epic, but for a Friday session, it’ll be a welcome change.
Saturday the 5th of September morning keeps that hope alive. The swell holds at 3 feet from the southeast with a 10-second period, and the wind stays offshore from the northeast at 9 mph, keeping it clean. Energy is still moderate at 159. This is your other chance to get a few, but don’t sleep on it—by the afternoon the wind swings onshore and it’s back to slop.
After that, it’s a sharp drop-off. The rest of the second week is mostly tiny, weak, and blown out again. The swell just fades away, and we’re left with little more than ripple-chasing.
So, to put it simply: if you’re keen, make the most of that Friday the 4th and Saturday the 5th of September. It’s not going to be a day for the history books, but it’s the only real surf in the forecast. Everything else, you might as well stay home and wax your board.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
